需要设置材质 lineMaterial.SetPass(0);
Material lineMaterial;void CreateLineMaterial()    {        Shader shader = Shader.Find("Hidden/Internal-Colored");        lineMaterial = new Material(shader);        lineMaterial.hideFlags = HideFlags.HideAndDontSave;        //设置参数        lineMaterial.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.SrcAlpha);        lineMaterial.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);        //设置参数        lineMaterial.SetInt("_Cull", (int)UnityEngine.Rendering.CullMode.Off);        //设置参数        lineMaterial.SetInt("_ZWrite", 0);    }    private void Awake()    {        CreateLineMaterial();    }private void OnPostRender()    {        DrawMutilLine();    }void DrawMutilLine()    {        List<Vector3> posList = new List<Vector3>();        posList.Add(new Vector3(0.3f, 0.6f, 0));        posList.Add(new Vector3(1.2f, 1.8f, 0));        posList.Add(new Vector3(0.6f, 2.4f, 0));        posList.Add(new Vector3(1.5f, 2.7f, 0));        if (posList.Count < 2) return;        lineMaterial.SetPass(0);        GL.Begin(GL.LINES);        GL.Color(Color.green);        for (int i = 0; i < posList.Count - 1; i++)        {            GL.Vertex(posList);            GL.Vertex(posList[i + 1]);        }        GL.End();    }
